Patent JP-2008546541-A (JP)
IPC: B08B7/00
Filed: 2006-06-10
Abstract: The invention relates to a device (10) and a method for cleaning contaminants from an arc welding torch or cutting torch using a cold jet of an agent which is applied to the individual functional parts of the torch by means of a jet nozzle. The jet nozzle comprises at least two concentric exit regions (22, 24) for the jet and configured to form at least two sub-streams with different flare angles in order to simultaneously and comprehensively expose all the functional parts of the torch that are to be cleaned to the cold jet. This permits a large tolerance range for the positioning of the torch head in relation to the positioning of the jet nozzle without having a detrimental effect on the cleaning result.
